WARM-UP
Values of R, the ideal gas constant, and the ideal
gas equation are given below. Use these to solve
the problems.
R=0.08206 L atm/mol K-8314LkPa/mol K
PV = nRT
A 10.0-L rigid container holds 3.00 mol H2 gas at a
pressure of 4.50 atm. What is the temperature of
the gas? (Round to the nearest whole number)

DONE

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
